This is the TransactionAttributes
module TransactionAttributes
def success
success
end
def success=(success)
self.success = success
end
def errors
errors
end
def errors=(errors)
self.errors = errors
end
end
The reason for these was i was trying to set a property on a returned
object or the errors. I yet to figure out a way i can return a more
descriptive error message from the transaction back to the controller.
I'll fix the style note. That just happens to populate when using a tab
trigger in Sublime.
This is the table schema
# == Schema Information
#
# Table name: resources
#
# id :integer not null, primary key
# resource_name :string(255)
# teacher_id :integer
# student_id :integer
# source_id :string(255)
# created_at :datetime not null
# updated_at :datetime not null
# resource_type :string(255)
#
The SystemStackError - stack level too deep:
actionpack (3.2.13) lib/action_dispatch/middleware/reloader.rb:70:in `'
is the only thing i get in the console.
This is whats returned in the response.
SystemStackError at /resources
